T (1% whom it may concern:

Be it known that I,JAMES BUOKLEY, retired cotton-mill manager, a subject of the Queen of Great Britain and Ireland, residing at 51 Mount Pleasant, Liverpool, in the county of Lancaster, England, have invented Improvements in or Relating to Spinning Machinery, which are also applicable to doubling machinery. of which the followingis a specification.

This invention refers to improvements in or relating to machinery, such as ring-frames and others, for spinning and doubling cotton, wool, and other fibrous materials, and has for its object the making of firmer and more reliable yarn, free from soft places and less waste than hitherto. The invention is equally applicable to machines for spinning on the bare spindle or bobbin.

To carry my invention into effect, when commencing the windin g of cops the drawingrollers are driven at a constant speed, but as the cop-bottoms are being formed I drive the drawing-rollers at a variable speed. When the cop-bottoms are formed, the maximum speed is imparted to the drawing-rollers when commencing the chase and is gradually reduced to a minimum as the end of the chase or the bare spindle is reached. By these means the drawing-rollers deliver the greatest amount of yarn when it is most required' viz., when winding on the thickest portion of the cop-nose, the supply being gradually diminished as the yarn is wound on the thinner portion of the cop-nose.

In order that my invention may be more fully understood, 1 have attached hereto four sheets of explanatory drawings of the mechanism whereby my object is attained.

Figure 1 is so much of a front elevation of a ring-spinning or doubling frame as is necessary to illustrate my invention. Fig. 2 is a plan of same. Fig. 1, looking in the direction of the arrow a. Fig. 4 is sectional plan through the line A B, Fig. 3. Fig. 4 is a side elevation of a mutilated worm-wheel constructed to allow the regulator to drop out of gear automatically when the cop-bottom is formed. Fig. 4 is a View of a detail. Fig. 5 is a plan view Fig. 3 is an. end elevation ofv of the main driving-shaft and connections.

Fig. 6 is an end View of the heart-cam and dies. Fig. 7 is a side view of Fig. 6. Fig. 8 is a sectional elevation of Fig. 1 on the line C D, looking in the direction of the arrow 1). Fig. 9 is a back elevation looking in the direction of the arrow 0, Fig. 4. Figs. 10 and cylinders 6, the main driving-shaft 7, and the usual fast and loose pulleys 8.

In the frame end 1 of the machine I mount a shaft 9, upon which is mounted a spurwheel 10. The spur-wheel 10 is provided with a slot 11, in which slides a diamond or block 12, carrying astud 13, which is secured to a stud-Wheel 14. The stud-wheel 14 is formed with spur-wheel teeth and is carried on a stud 15," secured to the upper end of a radial arm 16. The other end of the stud 15 is fixed to a sliding block 17, carried in aslot 18, formed in the bar 19. The bar 19 is secured to the frame 1 by end brackets 20. To the block 17 is attached a nut 21, screwthreaded to receive a threaded regulatingspindle 22, mounted in bearings 23, carried by the bar 19. The radial arm 16 carries a pin or axis 24, engaging with a slot 25, formed in the arm 16. The radial arm 16 is secured to a slotted lever 32 by means of a stud 33 as shown in Figs. 3 and 8. On the pin24 are loosely mounted a spur-pinion 26 and spur-wheel 27, connected together, the pinion 26 gearing with the stud-wheel 14 and thespur-wheel 27 gearing with a pinion 28, loosely mounted on the stud 29. Upon the stud 29 are also loosely mounted spurwheels 30 30, (see Figs. 1, 3, and 5,) gearing with spur-pinions 31 31 on the main drivingshaft 7. (See Fig. 5.) The pinion 28 and spurwheels 30 3O are connected so as to revolve together. The spur-pinions 31 31 are mounted loosely upon the shaft 7 and are provided with the clutch-boxes 32 and 33, respectively, which are operated by the forks 34 on the sliding bar 35, mounted in the bracket 36, secured to the frame of the machine. The sliding parts of the clutch-boxes 32 33 are driven by the keys or feathers 37 on the shaft 7. lVhen the machine or frame is set in motion on the commencement or formation of the cops and when the spindles or bobbins are bare, the slotted wheel 10 and stud-wheel 14 are concentric to each other, as shown in Figs. 1, 2, 3, 4, 5, and 8, and the clutch-box 32 is in gear. The spur-pinion 31 has one or more teeth less than the spur-pinion 31 for the purpose of reducing the speed of the d rawing-rollers when commencing to spin on the bare spindle, so as to prevent soft yarn. The sliding clutch half of the clutch-box 32 is held in gear by the pin 38, mounted in the slide-fixing 3G. The pin 38 drops into a notch in the edge of the sliding bar 35, by which it is held until a sufficient portion of the cop has been spun. \Vhen the driving-shaft 7 is rotated to drive the machine or frame, the gearing 31, 30, 28, 27, and 20 are operated to drive the stud -wheel 14, which drives the slot-wheel 10 by means of the stud 13 and diamond or block 12 in the slot 11.

To obtain the variable speed of the drawing-rollers, the stud-wheel 14 must be arranged eccentrically to the slot wheel 10, which is gradually effected during the formation of the cop-bottoms and in the following manner: The rotation of the slot-wheel 10 operates the shaft 9 and worm 39, the latter gearing into the worm-wheel 40 on the shaft 41 in the fixings or bearings 42. On the shaft 41 is fixed the worm 43, gearing into the wormwheel 44 on the shaft 45. The shaft 45 is mounted in the bearings 46 and is fitted with the bevel-wheel 47, gearing into the bevelwheel 48 on the spindle 22, by which the latter is driven to regulate the position of the stud 14 and place it gradually in an eccentric position to the slot-wheel 10 until the copbottom has been formed. When the cop-bottom has been formed, the worm-wheel 44 will have been rotated to bring the part devoid of teeth (shown in Fig. 4) under the worm 43, by which the regulation of the stud-wheel 14 will cease. The requisite degree of eccentricity of the stud-wheel 14 to the slot-wheel 10 has then been attained. The shaft 45 is provided with the key or feather 49 to allow of the worm-wheel 44 being slid out of gear when resetting the stud-wheel 14 into a concentric position with the slot-wheel 10 for the next set of cops. Before this greatest degree of eccentricity is, however, attained and ata period when the cop-bottoms are about half formed it is desirable to increase the speed of delivery of the yarn owing to the increasing size of the cop-bottoms. This is effected by means of the pivoted lever 51, which is op- 54 in such a manner as to pull the clutch-box 32 out of gear with the pinion 31 and put the clutch-box 33 in gear with the pinion 31 (See Figs. 10 and 11. As has already been mentioned, the pinion 31 is provided with one or more teeth in excess of the pinion 31, and thus the requisite slightincrease of speed of the drawing-rollers through the intermediate gearing is attained.

It will be understood from the foregoing description that although the slot-wheel 10 revolves upon the shaft 9, yet the stud-wheel 14, carried by the radial arm 16, by which the slot-wheel 10 is driven, has been gradually shifted during the formation of the cop-bottom from a concentric to an eccentric posi tion relatively to the slot-wheel 10. There fore as the stud-wheel 14 revolves eccentrically to the slot-wheel 10 the sliding of the diamond or block 12 within the slot 11 creates a differential speed of the slot-wheel 10, although the speed of the stud-wheel 14 is constant. The maximum speed of the slot-wheel 10 is attained when the block 12 is moved by the stud-wheel 14 to the position in the slot 11 nearest to the center of the slot-Wheel 10 and gradually approaches its minimum as the block 12 is moved outward toward the periphery of the slot-wheel 10. The drawingrollers 5 are driven from the slot-wheel 10, and therefore receive a variable speed. This variable speed is arranged to be commenced at a maximum when commencing the chase of the cop-nose and is gradually reduced toa minimum when winding on the bare spindle at the end of the chase. The drawing-rollers therefore deliver the greatest amount of yarn at the time when it is required-Viz., when winding on the thickest portion of the copnose-gradually reducing the'supplyof yarn as the bare spindle is approached. The apparatus thus effects a more regular twist and more uniform yarn than hitherto, giving the same number of turns or twist to the yarn per inch both at the thickest and at any other point of the chase.

The drawing-rollers 5 are driven from the slot-wheel 10 in the usual and well-known manner, as indicated more particularly in Figs. 12 and 13, Sheet 4. A bracket 55 carries a stud 56, upon which is mounted two pinions 57 and 58 secured together. .(See Fig. 3.) The pinion 57 is driven by the slotwheel 10, and by means of the connected pinion 58 drives a pinion 59 secured upon the axis 60 of the front drawing-rollers. Upon the axis 60 is secured a pinion 61 gearing with a pinion 62 secured upon a stud 63, which also carries a pinion 64 gearing with and imparting motion to a pinion 65 on the axis of the back drawing-rollers. The middle drawing-rollers are driven by means of a pinion 66 on the axis of the back drawing-rollers, which gears through an intermediate wheel with a pinion 67 keyed on the axis of the middle drawing-rollers, being employed to give them the required opposite direction of motion.

The copping-motion is operated and regulated by the movements of the slot-wheel 10 on the shaft 9. On the shaft 9 is mounted a bevel-wheel 58, gearing with a bevel-wheel 59 on the inclined shaft 60. (See Figs. 3 and S.) The shaft 60 is also provided with a bevel- Wheel 61, gearing with the bevel-wheel 62, mounted upon the heart-cam shaft 63, thereby communicating the requisite motion to the heart-cam shaft. To assimilate the winding of the ring-frame to that of the mule and thereby render the cop-nose less liable to pull to waste, I provide, in conjunction with the ordinary bowl, two dies or followers to work with the heart cam 64, as shown in Figs. 6 and 7, by which the same will reduce friction and allow of a speedy change when winding on the cop-nose. The dies 64 are mounted on the copping-lever 66 on each side of the ordinary bowl 67. The heart-cam 64 is increased in thickness at the end to operate on the dies 65, but is of the ordinary thickness in the remaining part to operate on the bowl 67. As shown in Fig. 7, the heartcam 64 is revolving in the direction of the arrow. The thickened portion of the heartcam is shown from a to b and from this portion a to b the heart-cam leaves the bowl 67 and slides upon the dies 65. In the position shown in Figs. 6 and 7 the point of reversal of the ring-rail 2 has been reached. The thickened portion of the heart-cam 64 drops rapidly down the side of the dies 65 upon the bowl 67, by which means a rapid reversal of the ring-rail is obtained and soft cop-nose avoided. This arrangement produces winding on the cop-nose when traveling downward, as shown in Fig. 14, and is a facsimile of that produced on the ordinary spinning-mule. The lever 66 is connected to the pulley 68 on the shaft 69 by means of achain 70. The shaft 69 is supported in bearings 71, attached to the frame end 1. On the shaft 69 is fixed the pulley 7 2, to which is secured the chain 73 to connect it with the quadrant 7 4 on the shaft 75. The shaft 75 is fitted with the lever 76, to which is pivoted the upright 77, secured to the copping-rail 2. The

upright 77 is mounted in the bearings 7 8 in the bolster-rail 3. It must be understood that this method of imparting the requisite motion to the ring-rail through the copping-lever and quadrant is old and forms no part of my invention.

I claim 1. In combination, the drawing-rollers, the copping-motion, a drive-shaft and means intermediate of said rollers and copping-motion and the driving-shaft for imparting a differential motion, consisting of two wheels having a sliding connection between them, one of said wheels having geared connections with the drive-shaft, and the other being in connection with the drawing-rollers and coppingmotion and means for automatically adjusting one of said wheels in relation to the other to change from a concentric to an eccentric relation, substantially as described.

2. In combination, the drawing-rollers, the copping-motion, a drive-shaft and means intermediate of said rollers and copping-motion and the driving-shaft for imparting a diiferential motion, consisting of two wheels having a sliding connection between them, one of said wheels having geared connections with the drive-shaft, and the other being in connection with the drawing-rollers and coppingmotion, means for automatically adjusting one of said wheels in relation to the other to change from a concentric to an eccentric relation, and clutch-boxes on the drive-shaft with means for automatically changing them, substantially as described.

3. In combination in a copping-motion, the copping-lever, the two dies 65, the intermediate roller and the heart-shaped cam having a thickened portion to engage the dies and a thin portion to engage the roller, substantially as described.

4. In combination, the drawing-rollers and copping-motion, the driving-shaft, the studwheel 14, the gearing between the same and the driving-shaft, the slot-wheel 10 having a sliding block connected with the stud-wheel 14, the gearing between the slot-wheel and drawing-rollers, the geared connections between the slot-wheel and the copping-lever, the movable bearing for the stud-wheel14 and means for automatically operating the same consisting of the screw-shaft 22, the shaft 9 of the slot-wheel 10 and the gearing between the shaft 9 and the shaft 22 substantially as described.

In witness whereof I have hereunto set my hand in presence of two witnesses.
